Tb lines

Have the html5 version show tb lines again. (the faded lines that showed the tb'd units "moving").
Makes it easier to see when someone got tb'd and would help against arguments

I think they are working on it, and btw thx on internet explorer the game works just fine xD

They should be shown (unless it's a bug and they're not)

I think this is a bug on sl as well, sometimes there are no grey lines but people appear to be tbed.
